The anomaly that was not meant IIB
Fortschritte der Physik, Volume 70, Issue 1, January 2022., 2022 Abstract Type IIB supergravity enjoys a discrete non‐Abelian duality group, which has potential quantum anomalies. In this paper we explicitly compute these, and present the bordism group that controls them, modulo some physically motivated assumptions.

Fundamental Units of Measurement and Extra Dimensions
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 The space available to our perception is three-dimensional with full evidence. The development of physics led to the hypothesis of extra dimensions. It is believed that an important role in the unification of physics should play by the Planck units of mass, length and time, built on the universal constants c (the speed of light in a vacuum), G (the ...

Seeking de Sitter vacua in the string landscape [PDF]
Proceedings of Corfu Summer Institute 2022 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2022), 2023 In this report, we present a concise review on the various moduli stabilisation schemes proposed in the context of type IIB superstring compactifications using Calabi-Yau orientifolds.

Supersymmetric Dyons, Superstrings, and Rotating Wormholes
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We construct supersymmetric dyon solutions based on the ‘t Hooft/Polyakov monopole. We show that these solutions satisfy κ‐symmetry constraints and can therefore be generalized to supersymmetric solutions of type I SO(32) string theory. After applying a T‐duality transformation to these solutions, we obtain two D3‐branes connected by a wormhole ...

On K3-fibred LARGE Volume Scenario with de Sitter vacua from anti-D3-branes [PDF]
Journal of High Energy Physics, 2022 In the context of type IIB superstring compactifications on K3-fibred (weak) Swiss-cheese Calabi Yau (CY) orientifolds, we consider the realisation of de Sitter vacua obtained through the introduction of an D 3 ¯ $$ \overline{D3} $$ -brane at the tip of ...

Double Copy from Homotopy Algebras
Fortschritte der Physik, Volume 69, Issue 8-9, September 2021., 2021 It will be shown that the BRST Lagrangian double copy construction of N = 0 supergravity as the ‘square’ of Yang–Mills theory finds a natural interpretation in terms of homotopy algebras. The authors significantly expand on their previous work arguing the validity of the double copy at the loop level, and they give a detailed derivation of the double ...

String (Gravi)photons, “Dark Brane Photons”, Holography and the Hypercharge Portal
Fortschritte der Physik, Volume 69, Issue 6, June 2021., 2021 Abstract The mixing of graviphotons and dark brane photons to the Standard Model hypercharge is analyzed in full generality, in weakly‐coupled string theory. Both the direct mixing as well as effective terms that provide mixing after inclusion of SM corrections are estimated to lowest order.

Journal of High Energy Physics, 2021 We examine the mechanism of moduli stabilization by fluxes in the limit of a large number of moduli. We conjecture that one cannot stabilize all complex-structure moduli in F-theory at a generic point in moduli space (away from singularities) by fluxes ...

Inflation, gravity mediated supersymmetry breaking, and de Sitter vacua in supergravity with a Kähler-invariant Fayet-Iliopoulos term [PDF]
Physical Review D, 2021 We use a new mechanism for generating a Fayet-Iliopoulos term in supergravity, which is not associated to an R symmetry, to construct a semi-realistic theory of slow-roll inflation for a theory with the same K¨ahler potential and superpotential as the ...

An Effective Model for Glueballs and Dual Superconductivity at Finite Temperature
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The glueballs lead to gluon and QCD monopole condensations as by‐products of color confinement. A color dielectric function G(∣ϕ∣) coupled with a Abelian gauge field is properly defined to mediate the glueball interactions at confining regime after spontaneous symmetry breaking (SSB) of the gauge symmetry. The particles are expected to form through the
